Operation Manual

ZS-MICTEK ZS-CUT50DP Air plasma cutting technology Plasma cutters work by passing an electric

arc through a air/gas that is passing through a constricted opening. The gas can be air, nitrogen, argon, oxygen. etc.

The electric arc elevates the temperature of the gas to the point that it enters a 4th state of matter. We all are familiar

with the first three: i.e.,Solid, liquid, and gas. Scientists call this additional state plasma. As the metal being cut is part

of the circuit, the electrical conductivity of the plasma causes the arc to transfer to the work. The restricted opening

(nozzle) the gas passes through causes it to squeeze by at a high speed, like air passing through a venturi in a

carburettor. This high speed gas cuts through the molten metal.

Plasma cutting was invented as the result of trying to develop a better welding process. Many improvements

then led to making this technology what it is today. Plasma cutters provide the best combination of accuracy, speed,

and afford ability for producing a variety of flat metal shapes. They can cut much finer, and faster than oxy-acetylene

torches.。

Part 1: Machine Introduction

1. Current display meter

The digital Ammeter is used to display the actual output current of the power source.

2. Fault light

When the welding load is overloaded and the output current of the machine is too large, this light will be on. This situation is

normal and the machine can be restored; when there is damage inside the machine, this light will be on. In this case, the

machine is abnormal and requires maintenance.

3. Power indicator light

Turn on the power, this light will be on.

4. Adjust the value knob

Clockwise rotate to enlarge the current, and anti-clockwise rotate to reduce the current

5. Cutting gun control socket

Two-core aviation socket, cutting gun trigger switch control connection

Good ventilation is of critical importance for the normal performance and service life of this equipment. 2.2 Thermal Overload protection. Should the machine be used to an excessive level, or in high temperature environment, poorly ventilated area or if the fan malfunctions the Thermal Overload Switch will be activated and the machine will cease to operate.

Version Number: ZS-CUT50DP-20210204A1 The plasma cutting machines are typically more expensive than oxy/acetylene. Also, oxy/acetylene does not require access to electrical power or compressed air which may make it a more convenient method for some users. Oxyfuel can generally cut thicker sections (>63/64 inch) of steel more quickly than plasma. 10.

Version Number: ZS-CUT50DP-20210204A1 2.2 Hand torch cutting technique. When cutting make sure that sparks are exiting from the bottom of the work piece. If sparks are spraying up from the work Piece, you are moving the torch too fast, or you don’t have enough amps set. Hold the torch vertical and watch the arc as it cuts along the line. When sparks are exiting from the bottom of the work piece, the arc has pierced through the material. When the pierce is complete, proceed with cutting. 2.3 Piercing.

The easiest way to reduce bevel is by cutting at the proper speed and height for the material and amperage that is being cut.
